Signal lamp for prompting right-turn vehicle to avoid pedestrians at crossroad

Abstract

The invention relates to a signal lamp for prompting right-turn vehicles to avoid pedestrians at a crossroad. The signal lamp comprises camera equipment, a signal lamp control unit and a right-turn prompting lamp, wherein the camera equipment is used for picking up real-time video images of a pedestrian crossing at the crossroad; the signal lamp control unit is used for analyzing the real-time video images by using a mode recognition algorithm, recognizing whether pedestrians walk in the area of the pedestrian crossing or not and transmitting control signals to the right-turn prompting lamp according to recognition results; and the right-turn prompting lamp is arranged at the front of a right-turn lane at the crossroad and is lighted up or extinguished according to the control signals. Therefore, the signal lamp for prompting right-turn vehicles to avoid pedestrians at the crossroad has the advantages that the drivers of the right-turn vehicles can be provided with visualized prompts aiming at the situation whether pedestrians walk on the pedestrian crossing at the front or not, the drivers can make a prejudgment of slowing down to give way or not, the situation of scrambling for passing between the right-turn vehicles and the pedestrians is improved and the maintenance of traffic safety is facilitated.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a warning signal lamp for vehicles turning right at intersections to avoid pedestrians. Background technique [0002] Today, with the increasing number of various motor vehicles, various warning lights are playing an increasingly important role in maintaining traffic safety and keeping traffic smooth. Especially at intersections, in order to coordinate the passing of motor vehicles in the direction of going straight, turning left and turning right, and pedestrians crossing the road, it is necessary to cooperate with multiple traffic warning lights. figure 1 It shows the existing typical intersection traffic lights and the flow direction of vehicles and pedestrians. When the straight running lights and the left-turn lights of the traffic warning lights 10 and 11 in the north-south direction were all red lights, the vehicles 20 that went straight and turned left along the n...

Problems solved by technology

Although in theory pedestrians have the right of way, right-turning vehicles 40 should avoid pedestrians 30 on the crosswalk, but in real life, the phenomenon of pedestrians and right-turning vehicles "rushing" on the crosswalk is very common and has become a traffic law. A major hidden danger of accidents, there have even been accidents of collisions with pedestrians on crosswalks due to vehicles not slowing down when turning right

One of the main reasons for this phenomenon is that the driver of the right-turning vehicle
